(cilia-i115) This invention relates to machines of the character' "thatemploy an, intermittently. rotatable dial feed toimoveabody; such as a container, into and out of position, and has forits main object feature the production of a compact and effective dial feed capable of use in high-speed machines.. i

1 indicates a reciprocatory pedestal to receive a body sucl as container 2, so that a cover 3 may be seamed to said body by seaming rollers 4 in a well understood manner. 5 indicates a dial feed, the wings of which move the containers from a suitable conveyor (not shown) to the pedestal and, after the seaming operation has been com- 6 is a dial feed shaft which is turned intermittently a fraction of a revolution to effect the discharge and feed of the containers. 7 is a camshaft, making here one revolution to each reciprocation of the pedestal, and this shaft carries a cam 8 that actuates cam lever 9, pivoted at 10, and thereby effects up and down movement of the pedestal by the forked end of said lever engaging yoke 11 having a spring 12 that engages collar 13 pinned At the lower end of the dial feed shaft is a clutch composed of two members 15 and 16, and carried by the pedestal is a clutch-controlling member 17 that engages a yoke on member 15 so that when the pedestal has risen to a certain level the clutch members become disengaged, and conversely when the pedestal has been moved downward to another level the clutch members engage. Clutch member 15 is fast on the dial feed shaft and member 16 is loose thereon. Carried by member 16 is a gear or pinion 18 that meshes with a gear sector 19 pivoted at 20 and oscillated by means of cam 21 and cam roll 22. Carried by clutch member 15 is a pluralityof pins 23 that successively engage a socket 24. Fin 23 engages socket 24 after the clutch members have become disengaged and thus serves as an alining means after each quarter turn of the dial feed shaft.

After the seaming operation has been completed, the pedestal descends and thereby disengages 23ffror n soc causes en agement ofthe m nace? members. 'The'reupon the dialfeed shaft begins to turn and continues to turn during the furtherdescent of the pedestal and also during the upwarda'scent ofthe pedestal until the clutch membersbecome disengaged, after which a. pin 23 ,again enters socket 24. During this period fa. container hasv been removed'fromtheipedestal by one wing of the dial feed and another has been positioned thereon by another wing of .the'dial feed. Itlwill be observed that gear sector is oscillates pinion 18, and it will be understoodfthatwhen' the gear sectormoves the pinion inone direction theclutch members are engaged 'that'ia partial turnis given @1 d fi$l;,.$ aftwwlf e eaalw e the ar sector. m v s th lfruiion "th i' e rection the membersoftheclutchare disengaged sothat said pinionf ndiclutchfmember 16 turn idly ontheidialfeedlshaft. p V

It will --be apparent that the" above-described construction forms a very compact device, and one that can be very accurately timed with but slight trouble. The construction has, however, other advantages which will appear from What follows. It has been customary in the prior art to employ a Geneva stop-motion to effect inter mittent turning of the dial feed shaft. The Geneva stop-motion is effective only during approximately 135 degrees of a revolution, and as this is a relatively small part of the working cycle it is necessary to move the container relatively fast. By the above construction however, the v limitations of the Geneva stop-motion are avoided because cam 21 can be, and is, so shaped that a part of its revolution much greater than 135 degrees can be utilized for the purpose of effecting the quarter turn of the dial feed shaft and hence the container can be moved more slowly without sacrificing the speed of the, machine. Furthermore, cam 21 is so shaped that a gradually accelerated and gradually decelerated movement is imparted to the container so that there is very little danger; of spilling the contents of the container even at high speeds. In the cam as shown a comparatively small part (from a. to a is devoted to the return movement of the sector which can obviously be made as quickly as desired and a relatively great portion is devoted to that movement which causes the dial feed shaft to turn. There is, of course, a dwell at two points in the cam (adjacent ct and 11. but even with these dwells a part of a revolution substantially be so used.
